Abstract
The utility model provides a mold ejection mechanism capable of breaking a side gate automatically. By the mold ejection mechanism, a product is separated from a gate automatically in a demoulding process, and the production efficiency of the mold is improved. The mold ejection mechanism comprises a front mold, a rear mold and a product ejection needle, wherein a cavity is formed between the front mold and the rear mold; a product is in the cavity; one side of the cavity is communicated with a gate structure; the gate structure is positioned at the side part of the mold cavity; the lower end of the product ejection needle penetrates through the rear mold and is fastened onto an overall structure formed by a surface needle plate and a bottom needle plate. The mold ejection mechanism is characterized in that the upper end of a gate ejection needle is propped against the gate structure; the lower end of the gate ejection needle is positioned in a mounting cavity formed by the surface needle plate and the bottom needle plate; the lower end of the gate ejection needle is supported on the upper end surface of a delay needle; the lower end surface of the delay needle penetrates through the bottom needle plate and is supported on a bottom seat; the upper part of the delay needle is of a cylindrical platform structure; the cylindrical platform structure is positioned in the mounting cavity.
Description
Technical field
The utility model relates to the technical field of structures of product mold, is specially a kind of mold ejection mechanism from dynamic circuit breaker side gate.
Background technology
Goods adopt the mode of side gate to enter glue, and mould structure can not be from dynamic circuit breaker cast gate, and goods and cast gate connect together, and this just needs following process to make goods separated with cast gate, and it makes the production efficiency of mould low.
Summary of the invention
The utility model provides a kind of mold ejection mechanism from dynamic circuit breaker side gate, and it is separated that it makes in knockout course goods and cast gate automatically complete, and has improved the production efficiency of mould.
A kind of mold ejection mechanism from dynamic circuit breaker side gate, its technical scheme is such: it comprises front mould, rear mold, described front mould, it between rear mold, is die cavity, in described die cavity, it is product, one side of described die cavity is communicated with pouring gate structure, described pouring gate structure is positioned at the sidepiece of described die cavity, it also comprises product thimble, the lower end of described product thimble is anchored on face needle plate after running through described rear mold, in the formed overall structure of end needle plate, it is characterized in that: the upper end of cast gate thimble is mounted on described pouring gate structure, the lower end of described cast gate thimble is positioned at described needle plate, in the installation cavity that end needle plate forms, the lower end of described cast gate thimble is supported on the upper surface that postpones pin, needle plate rear support of the described end is run through in base in the lower surface of described delay pin, the top of described delay pin is cylinder table structure, described cylinder table structure is positioned at described installation cavity, spacing is left in the lower surface of described cylinder table structure and the lower surface of described installation cavity.
It is further characterized in that:
The part that the bottom of described pouring gate structure is positioned at described rear mold is provided with back-off structure.
Adopt after structure of the present utility model, during the demoulding, front mould, after rear mold separation, face needle plate, the rising of end needle plate, now product thimble is driven rising, but be cylinder table structure owing to postponing the top of pin, described cylinder table structure is positioned at described installation cavity, spacing is left in the lower surface of described cylinder table structure and the lower surface of described installation cavity, make the cast gate thimble that is supported on delay pin upper surface can not increase at once, now in knockout course, goods complete separated with cast gate automatically, until the lower surface piling of cylinder table structure is when the lower surface of installation cavity, cast gate thimble just ejects pouring gate structure, complete the goods in mould, the demoulding of pouring gate structure, it makes goods in knockout course automatically complete separated with cast gate, improved the production efficiency of mould.
Accompanying drawing explanation
Fig. 1 is front view structural representation of the present utility model.
The specific embodiment
See Fig. 1, it comprises front mould 1, rear mold 2, front mould 1, it between rear mold 2, is die cavity 3, in die cavity 3, it is product, one side of die cavity 3 is communicated with pouring gate structure 4, pouring gate structure 4 is positioned at the sidepiece of die cavity 3, it also comprises product thimble 5, the lower end of product thimble 5 is anchored on face needle plate 6 after running through rear mold 2, in the formed overall structure of end needle plate 7, it is characterized in that: the upper end of cast gate thimble 8 is mounted on pouring gate structure 4, the lower end of cast gate thimble 8 is positioned at face needle plate 6, in the installation cavity 9 that end needle plate 7 forms, the lower end of cast gate thimble 8 is supported on the upper surface that postpones pin 10, end needle plate 7 rear supports are run through in base 11 in the lower surface that postpones pin 10, the top that postpones pin 10 is cylinder table structure 12, cylinder table structure 12 is positioned at installation cavity 9, space D is left in the lower surface of the lower surface of cylinder table structure 12 and installation cavity 9, the part that the bottom of pouring gate structure 4 is positioned at rear mold 2 is provided with back-off structure 13, it makes front mould 1, during rear mold 2 demoulding, pouring gate structure 4 is positioned at rear mold 2, can not glue front mould 1.
